---Do you know how this disabled man succeeded in running such a big company?
--- I don’t know , but I think he __________ many difficulties.

A.could have gone through B.must have gone through
C.might go through D.need go through

B

解析試題分析:句意:你知道這個殘疾人是如何成功地運營這么一個大公司的嗎?我不知道,但是我想,他肯定經(jīng)歷了許多困難。問句中succeeded用的是過去時,可知答句中應(yīng)該是對過去情況的推測。A、B兩個選項都可表示對過去情況的推測,但A選項的語氣很弱,意為:也許經(jīng)歷了不少困難吧。而根據(jù)問句中所說的殘疾人成功運營大公司,應(yīng)該推斷他肯定經(jīng)歷了不少困難。故選B。
考點:考查情態(tài)動詞+have done的用法。
